Title: Bonding rubbers to siliceous surfaces
IPC: C03C25/1095
Filed: 1961-04-11
Abstract: 937,254. Laminates. ESSO RESEARCH & ENGINEERING CO. April 11, 1961 [May 19, 1960], No. 12992/61. Class 140. Natural rubber, or a synthetic rubber such as polyisoprene, polybutadiene, a butadiene-styrene or -acrylonitrile copolymer, polychloroprene or a chlorinated or brominated copolymer of isobutylene and isoprene, is bonded to a siliceous surface such as glass sheet, flake, fibrous mat, cord or woven fabric, or ceramic material, by applying to the surface an unsaturated organic silane, applying the rubber and curing with an organic peroxide. Bonding may be further assisted by the use of a polyunsaturated monomer, such as divinyl benzene, which may be added to the rubber, applied, as a separate coating over the silane coating, either as such, as a blend with a minor proportion of a rubber (not necessarily that of the main rubber layer), or applied as a separate film made from such a blend. Part of the peroxide curing agent may be added to the polyunsaturated monomer or blend thereof. The unsaturated silane used is of the formula R n SiX 4-n , where R is an unsaturated hydrocarbon group such as vinyl-, allyl, methallyl-, or styrenyl-, X is halogen, or a hydroxy- or ether-group, and n is 1, 2 or 3. Examples are given. Polyunsaturated monomers used include, beside divinyl benzene, di- or tri-vinyl derivatives of substituted and unsubstituted benzene, naphthalene or phenanthrene, di- or tri-acrylates or methacrylates, esters such as divinyl adipate, triallyl cyanurate, diallyl phthalate or vinyl fumarate, polyvinyl ethers, and divinyl diethoxysilane. The peroxides used include dicumyl peroxide, ditert-butyl peroxide, 2,5-bis (tert-butyl peroxy)- 2,5-dimethyl hexane and benzoyl peroxide. In an Example (I) a glass plate is immersed for 30 minutes in an xylene solution of vinyl trichlorosilane, washed with water and dried, brushed with divinyl benzene, combined with a layer of natural rubber containing dicumyl peroxide, and cured at 300‹ F. under pressure. In other examples, (V) and (VIII), glass fabric is immersed in benzene to which the acid chloride of vinyl tri-(2-methoxy-ethoxy) silane is added dropwise up to 2¢%; the fabric is washed successively with benzene, isopropanol and water, dried with heat and vacuum, and placed between two layers respectively of compounded natural rubber, nitrile rubber and chlorbutyl rubber containing dicumyl peroxide, these layers being uncoated (V), and coated (VIII) with divinyl benzene, ethylene dimethacrylate, trimethylol propane trimethacrylate and triallyl cyanurate respectively, all coatings containing dicumyl peroxide, and heat cured under pressure.

Abstract: 553,535. Amino-hydroxynaphthalene sulphonic acids. GEIGY AKT.-GES., J. R. Oct. 9, 1941, No. 13035. Convention date, Oct. 10, 1940. [Class 2 (iii)] 1 - Amino - 6 - hydroxynaphthalene - 8 - sulphonic acid and 1 - amino - 7 - hydroxy - naphthalene - 5 - sulphonic acid are prepared by nitrating an acyl derivative of 2-hydroxynaphthalene - 4 - sulphonic acid, and reducing the nitro compound so produced. If desired the two acids may be separated by means of the different solubilities in water of their respective sodium salts. In an example 2- carbomethoxy - hydroxynaphthalene - 4 - sulphonic acid is treated with a mixture of sulphuric and nitric acids. The nitrated mass is then reduced by iron filings and acetic acid to give the mixture of amino-2-hydroxynaphthalene - 4 - sulphonic acids. To effect a separation of the two acids the reduction product is neutralized with caustic soda and crystallized. The isolated aminohydroxynaphthalehe sulphonic acids can be converted by known methods into their derivatives substituted in the amino group, and the preparation of 1-carbomethoxy-amino-6-hydroxynaphthalene - 8 sulphonic acid by treatment of the corresponding amino-sulphonic acid with chlorocarbonic acid methyl ester, and also the preparation of 1-benzylamino-7- hydroxynaphthalene - 5 - sulphonic acid by the treatment of the corresponding amino sulphonic acid with benzyl chloride are described.

Title: Improvements relating to automatic winding machines
Inventor: STANGE FERDINAND F
IPC: B65H63/00
Filed: 1958-04-28
Abstract: 880,019. Winding yarns; tensioning; slub-catching. FOSTER MACHINE CO. April 28, 1958, No. 13467/58. Class 120(2) A yarn tensioning and slub-catching device comprises a pair of slub-catching blades held in slub-intercepting relation to guide means for the yarn, means engaged by the yarn when in operation and operable to move the blades away from the guide means whenever the yarn breaks, tensioning members for the yarn and a pivoted lever operable by movement of the blades to move one tensioning member away from the other. As shown the frame 10 of a winding machine supports a tensioning and slub-catching apparatus on a crossbar 14. The slub-catcher consists of guide members or anvils 82 resiliently secured to the frame 84 and slub intercepting means comprising a pair of blades 86, 87 secured to hinges 91, 92 mounted on pivotable wire 89. The blade 87 has a straight edge whilst 86 has a serrated edge. The blades may be adjusted relative to the anvils 82 by screen 96. Also mounted on wire 89 is a block 100 which carries a lever arm 102 and has a lug 104 which engages a bent portion 106 of a pivotable wire 108. Fixed to wire 108 is a trip 110 for the pin 66 of the tensioning device 60. In operation should the yarn break a trip wire (not shown) is released and causes a knock-off lever to engage arm 102, movement of which rotates the block 100 and the pivotable wires 89, 108 thereby opening the blades 86, 87 and raising the cup 72 of the tensioning device. The apparatus is preferably used on a winding machine having a "tender" and the opening of the slub-catcher and the tensioner permits the easy withdrawal of the yarn by the tender. A rod 18 depends from the apparatus and has a flange 19 having a pair of pins 22 for supporting bobbin cores. The flange 19 is rotatable to enable a bobbin to be swung from the initial starting position A to the normal operative position B under the poteye 24. Means, jaws 28 and 29, are provided for temporarily positioning the found or trailing end of the package yarn and the leading end of the reserve yarn on the bobbin in the position A. The tender takes hold of the two ends and knots them. Because the knot is too large to safely pass through the tensioning and slub-catching devices the yarn is by-passed around these devices during the initial winding operation. To do this, with the reserve bobbin in position A the yarn passes over the body 50 of the spur guide 40, over the arm 48, along the curved end 58 of the guide bar 43 and into the passage-way 54 between the guide bars 42, 43. The knot is tested and tightened in the passage-way 54. As the bobbin moves to position B the yarn passes further to the left along slot 52 and rearwardly of the passageway 54 and finally it reaches poteye 24 and slides under the rearward end of guide bar 42 assuming the final position shown in Fig. 2. Specifications 684,812 and 701,558 are referred to.
